DVP Vacuum and Pressure Combined Dry Running Rotary Vane Vacuum Pumps

Working Principle Rotary Vane Pumps operate with a eccentrically mounted rotor within the pump body. The rotor has slots that accommodate the vane.  Under power the vanes are centrifugally pushed out forming a seal against the pump body, creating chambers of air.  As the eccentric rotor spins, this creates a pressure which can be used as a vacuum pump or a compressor, or in the case of combined pumps, both vacuum and pressure is available. Oil-free rotary vane pumps can run continuously both at atmospheric pressure and at the highest vacuum. However, they cannot be used when the aspirated air contains moisture, oil or other traces of liquid. All versions can be used as compressors.
